IMPROITEMENT IN COACH-CLEANING- SPONGE. ik

y.'Lhe Schedule referred to in these `Letters Patent and making part of the same.

N'QBeitknown that I', HENRY DIETRICH OHLsEN, of Chicago, in the county of` Cook and, Sgt-ate of Illinois,

`liaaie invented certain Improvement-s in Coaeh-Sponges,

of: which the following is a specification, reference heinghad to` theaccompanying drawing. l My invention relates "to` articles used for washing carriage-bodies and other polished surfaces, and coni'j 1in a novel construct-ion ofthe same by filling a net" with small pieces of` thoroughly-cleaned sponge,

and ,then attaching it` to a metallic holder, provided witha socket, in which a handle may be inserted.

` The drawing represents a perspective view ot' my .As is well'known, a `large piece` of common sponge is `ordinaril y used for washing carriage-bodies, the soft-V uess'aud elasticity of itsfsubstance making it exceedinglyfuseful for that purpose.A 1t however frequently happens that these large pieces of sponge have particles of hard earthymaterialtso deeply imbedded within, and closelyattached to them, that they cannot be thoroughly freed from them 'in the first instance, and that they ofteii`ji'oi'k loose, and work out, while the sponge is in use,`and lsoratch'aud otherwise injure the article being washed.

The-object of my invention is to produce a sponge carriage-washer that shall be entirely free from this objection, and shall, at the same time,preserve all the desirable qualities of the sponge. This I do bly-taking sponge of any` suitable quality, and cutting or tearing it up into small pieces, and then thoroughly cleaning `To all whom it may tonceofny these small pieces, so as to free them Yentirely from all grit, sand, and dirt of every kind. These pieces of sponge are then packed in anet-work bag, A, which is drawn Aclosely about them, as shown in the drawing. The bag A, with the sponge therein, is then attached to a metallic holder, D, consisting of a socket-handle., tt, extending downward intoa curved spreading jaw or plate, B, with a loosely-connected corresponding curved plate, C. by being placed between .these plates, and then held there by them, the plates being compressed `upon it by means of a screw-holt, b, as clearly shown in the drawing.

The sponge lthus arranged can be safely used for washing polished surfaces, and it is obvious that small and otherwise useless piecesyof sponge can be worked up to advantage.

It is also obvious that the sponge may be used without a holder, or that, when desired, a handle may he inserted in the holder.

Having thus described mv invent-ioni hat I claim is-- The herein-described apparatus tlor cleaning coaches and similar polished surfaces, said apparatus consist ing of the net-work sack A, filled with pieces of sponge, and held by the clamping-jaws B C, one of which Vis provided with a socket, for the application of a handle, substantially as described;
